Abstract

Biphenyl is used as an intermediate for synthesis of various pharmaceutical compounds. The objective of present research was to investigate the influence of biofield treatment on physical, spectroscopic and thermal properties of biphenyl. The study was performed in two groups (control and treated). The control group remained as untreated, and biofield treatment was given to treated group. The control and treated biphenyl were characterized by X-ray diffraction (XRD), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), Fourier transform infrared (FT-IR) spectroscopy, Ultravioletvisible (UV-Vis) spectroscopy and surface area analysis. The treated biphenyl showed decrease in intensity of XRD peaks as compared to control. Additionally, crystallite size was decreased in treated biphenyl by 16.82% with respect to control. The treated biphenyl (72.66ºC) showed increase in melting temperature as compared to control biphenyl (70.52ºC). However, the latent heat of fusion (?H) of treated biphenyl was substantially changed by 18.75% as compared to control. Additionally, the treated biphenyl (155.14ºC) showed alteration in maximum thermal decomposition temperature (Tmax) as compared to control sample (160.97ºC). This showed the alteration in thermal stability of treated biphenyl as compared to control. Spectroscopic analysis (FT-IR and UV-visible) showed no alteration in chemical nature of treated biphenyl with respect to control. Surface area analysis through Brunauer-Emmett-Teller analysis (BET) analyzer showed significant alteration in surface area as compared to control. Overall, the result demonstrated that biofield has substantially affected the physical and thermal nature of biphenyl.

Conclusion

The biofield treatment has shown substantial impact on physical and thermal properties of biphenyl. XRD result showed substantial reduction in crystallite size of treated biphenyl by 10.04% as compared to control. This may be due to presence of internal strain and atomic displacement from their ideal lattice positions that caused change in crystallite size. DSC of treated biphenyl showed an increase in melting temperature by 3.03% with respect to control. Nevertheless, the treated biphenyl showed substantial change (18.75%) in latent heat of fusion with respect to control. However, TGA showed alteration in thermal stability of the treated biphenyl with respect to control. The spectroscopic analysis using FT-IR and UV analysis showed no changes in the chemical nature of treated biphenyl as compared to control. BET analysis showed alteration in surface area in treated biphenyl with respect to control. The lower crystallite size of biofield treated biphenyl could improve the rate of reaction and this may improve the reaction yield. Hence, it is assumed that biofield treated biphenyl could be used as effective intermediate for synthesis of pharmaceutical compounds.
